'Baker Instra-Analyzed' Acids for Trace Metal Analysis

Produced by J. T. Baker, these reagents are quality controlled to provide low analytical blank values for more than 25 trace elements... low enough to make them suitable for most multi-element trace metals analysis via emis­ sion spectroscopy, atomic absorption and ICP. Examine the label.

Low blank values for over 25 key trace elements Actual lot analysis on the l a b e l . . . proof of purity Convenient pack­ aging . . . in 1 pint and 5 pint flint glass bottles

If your work requires even lower imparity levels, we1 recommend our ULTREX* acids . . . the standard for reagent purity throughout tho world.
